DETAILED DESCRIPTION OF THE DISCLOSURE

The present disclosure provides for a storage container assembly. In one example, the disclosed storage container assembly can be used for storing food as well as eating utensils and the like. The storage container assembly includes a primary storage container and a secondary storage container connected to the primary container. Each storage container has a lid that connects to and seals with a base. In one embodiment, the secondary container is sized to store eating utensils separate from food items stored in the primary container. The storage container can be made of any suitable material, but in the disclosed example is made of a plastic material such as polypropylene or polyethylene. The storage container may be categorized as disposable or semi-disposable when made of thin, inexpensive plastic because the storage container may be disposed of after one or more uses. Further, the storage container assembly may be formed from any one of a number of processes, such as thermo-forming, vacuum forming, pressure forming and/or injection molding.

Referring now to FIG. 1, one example of a storage container assembly 10 constructed in accordance with the teachings of the present invention, includes a primary storage container 12 and a secondary storage container 14 nested with and connected to the primary storage container 12. The secondary storage container 14 is positioned on top of the primary container 12 and in this example is smaller in size than the primary storage container 12. It should be understood that the secondary container may be larger than the primary container in alternate configurations. It should also be understood that the secondary container may be configured to connect to the primary container other than on top of the primary container.

Referring now to FIG. 2, the secondary storage container 14 can be separated from the primary storage container 12 in a manner that will be described in further detail below. The disclosed secondary storage container 14 has a pair of rounded end sections 16 a, 16 b and a pair of substantially linear, elongate side portions 18 a, 18 b. The primary storage container 12 can be similar in shape to the secondary storage container 14, as in this example. The primary storage container 12 has a pair of rounded end sections 20 a, 20 b and a pair of substantially linear, elongate side portions 22 a, 22 b. Alternatively, each storage container 12, 14 may have different shapes such as square, rectangular, or other geometric configurations as desired and need not be substantially similar in shape.

Referring now to FIG. 3, the primary container 12 includes a primary base 24 and a primary lid 26. A primary storage space 28 is created within the interior of the primary base 24 and primary lid 26 with the primary lid in the closed position shown in FIG. 2. When the primary lid 26 is in the open position of FIG. 3, the storage space 28 is accessible. Similarly, the secondary storage container 14 includes a secondary base 30 and a secondary lid 32. A secondary storage space 34 is created within the interior of the secondary base 30 and lid 32 when the secondary lid 32 is in the closed position as shown in FIG. 2. The secondary storage space 34 is accessible when the secondary lid 32 is in the open position of FIG. 3. In the embodiment illustrated in FIG. 3, the primary lid 26 is completely separable from the primary base 24 while the secondary storage lid 32 is connected to the secondary storage base 30 with a living hinge 36 along the elongate side portion 18 a. It should be understood that either lid 26, 32 may be connected to their respective bases 24, 30 by a hinge, or may be completely separable.

A recessed cavity 40 is formed in a top surface 42 of the primary lid 26 in this example. The recessed cavity 40 includes a lower surface 44 and a perimeter wall 46 extending upward from the periphery of the lower surface 44 to the top surface 42.

A snap fit mechanism 50 (best seen in FIG. 4) is provided to releasably connect the secondary storage container 14 to the primary storage container 12. The disclosed example of the snap fit mechanism 50 includes four protrusions 52. The protrusions 52 are arranged such that two are positioned spaced apart along each side 22 a, 22 b of the perimeter wall 46. The protrusions 52 are operable for resiliently engaging or snapping into complimentary receptacles 54 formed in the secondary base 30 of the secondary container 14. The protrusions 52 are snapped into the corresponding receptacles 54 when the secondary base 30 is positioned within the recessed cavity 40 of the primary lid 26.

The primary base 24 has at least one partition 60 in this example that divides the primary storage space 28 into separate storage compartments 62, 64. While not shown, it should be understood that the storage space can be formed without any partition or may have several partitions. Further, a partition can be formed in the primary lid 26 that is opposed to the base 24. The partition 60 in the depicted example is shown in a lateral orientation, but one or more longitudinally disposed partitions are also contemplated by the present disclosure. It should also be understood that the secondary container 14 may also include partitions in a similar manner disclosed in the primary container 12.

The primary lid 26 may also include a flap 80 extending outward from the top surface 42 thereof for a user to grasp when opening the lid 26 from the primary base 24. Likewise, the secondary container lid 32 may include a flap 82 extending outward from a perimeter 72 of the lid 32 for a user to grasp when opening the lid 32 from the secondary base 30.

FIG. 4 shows a cross-sectional view of the disclosed storage container assembly 10 more clearly depicting the snap fit mechanism 50. The secondary base 30 is nested within the recessed cavity 40 of the primary lid 26. Each protrusion 52 of the primary lid 26 extends into a corresponding receptacle 54 of the secondary base 54 to hold the secondary container 14 in a fixed position relative to the primary container 12. A distance D1 between the protrusions 52 must necessarily be less than the distance D2 between opposing side walls 86 a, 86 b of the secondary base 30 to prevent the secondary container 14 from inadvertently separating. As the secondary base 30 is pushed down over the protrusions 52, the protrusions 52 are resiliently displaced outward as they slide past the side walls 86 a, 86 b. Once the protrusions 52 align with their corresponding receptacles 54 of the secondary base 32, the protrusions 52 will resiliently snap into the receptacles 54 and thus hold the secondary container 14 in a snap fit manner to the primary container 12.

It should be understood by one skilled in the art that the protrusions 52 and the receptacles 54 can alternatively be positioned on the secondary base 30 and primary lid 26, respectively. Also, the number and position of protrusions 52 and receptacles 54 can vary in any manner desired. Furthermore, depending on the material selection and the thickness of the sidewalls 86 a, 86 b of the secondary base 30, the sidewalls 86 a, 86 b may also be displaced inward when the containers 12, 14 are snapped together. It should also be understood that other mechanical locking mechanisms such as dovetail joints, etc., as is known to those skilled in the art, can be employed to connect the containers 12, 14 together. Likewise, other materials such as glass, metal, or ceramic can be used with alternate locking mechanisms.

The lids 26, 32 sealingly engage with their respective bases 24, 30 via a tongue and groove connection as is known to those skilled in the art. The primary lid 26 includes a tongue 65 in this example that sealingly engages with or seats in a groove 66 formed around a perimeter 68 (see FIG. 3) of the base 24. In a similar manner, a tongue 70 formed around the perimeter 72 (see FIG. 3) of the secondary lid 32 engages with or seats in a groove 74 formed around a perimeter 76 of the secondary base 30.

Referring now to FIGS. 5 and 6, an end view and a side view of the nestable container 10 are respectively illustrated. When the primary and secondary containers 12, 14 are nested together, the base 30 of the secondary container 14 rests below the top surface 42 of the primary container 12. In this manner, the bottom surface 90 of the secondary container 14 is at least partially positioned below the top surface 42 of the primary lid 26.

In operation, the nestable storage container 10 can be used to store items separate from one another. In one example, the primary storage container 12 may store various food items (not shown) while the secondary container 14 may be used to store eating utensils (not shown). The eating utensils may include items such as forks, spoons, and knives for picnics, lunches away from home or similar functions. While the secondary storage container 14 may be sized to store any type of utensil such as standard silverware or serving utensils, it may alternatively be used to store additional food products.

Initially, a user can fill the primary container 12 with one or more desired items, such as food, and snap the primary lid 26 onto the primary base 24 to seal the storage space 28. A user can then place one or more additional items, such as eating utensils into the secondary storage container 14 and close the lid 32 onto the secondary base 30 to seal the storage space 34. The secondary storage container 14 is then pressed into the recessed cavity 40 of the primary lid 26 until the protrusions 52 of the primary lid 26 snap into the receptacles 54 of the secondary base 32. In order to remove the secondary container 14 from the primary container 12 a user merely grasps the flap 82 or another location along the outer perimeter 68 of the secondary container 14, and pulls upward to release the protrusions 52 from the receptacles 54. The secondary container 14 is then displaced upward from the primary container 12.
